when i fire up the car in -20 or so regardless of being plugged in (oil pan heater) it makes a horrible sound like marbles in a rock crusher for a minute or 2, and has a super lopey idle (brap brap brabrbrbrap) then it will stop making the noise and immediately assume a lower more calm idle.
doesnt seem like its an issue of no oil getting to somewhere although it definitely sounds like it...even though i am getting oil pressure almost immediately and it doesnt matter if the oil is cold or if ive been running the oil pan heater for several hours.

also doesnt matter if the clutch is disengaged or not so its nothing to do with transmission, what the heck could it be?

 

really? no replies?

 

The rock crusher or marbles sound is generally associated with pinging/knocking.

 

would the engine not be destroyed by that pretty quickly though?
also how could it be that the engine is knocking when running stupidly rich from a super cold start? it shoots out a massive cloud of what smells like pure fuel lol you'd think that would be enough to prevent any detonation..

i just find it weird that it goes away at the exact second the crazy 2000rpm braptastic idle goes away (which by the way sounds freaking awesome...just not the grinding sound that goes along with it lol)
